i the same.

My invention relates to'plastio floor coverin Afil ong the objects of my invention are To reduce a plastic floor covering which is app ied'in a plurality of coats each having certain characteristics so that permanent unions are secured between the floor and the next adjacent coat and between succeeding coats of the covering.

To devise a process for applymg a plastic covering comprising a plurality of coats to floors so that permanent unions are secured between the floor and the next ad acent coat and between succeeding coats of the cover in s.

I %Iy improved fioor covering is composed of a plurality of coats and some of the coats have qualities differing from those of the others,- but all have the quality of forming firm and lasting unions with HdJaCBDlZ coats and the first priming coat forms a s1m1lar union with the floor.

In thedrawing, which shows a section of a floor covering applied according to my invention: v

- l'represents the floor, which maybe formed of any material; 2 and 3 represent the primings coats, which may be formed of a solution of any suitable material, one of the requisites being that the coat 2 will form a firm and lasting union with the floor, and

that the coat 3 will form a similar union with the coat 2.

I have found that a solution of bitumen in any of its solvents and having a consistency rendering it suitable of application in even coats by either a brush or spray is suitable for priming the floor 1. I After the priming coats 2 and 3 are put upon the floor 1, I apply the coats 4 and 5;

The coats-4 and 5 may be composed of' various substances, one of the requisites being that the coat i will form a firm and last. ing union with the coat 3 and that the coat 5 will form a similar union with the, coat 4;.

I have found that the coats 4 and 5 may be made of? a solution of bitumen in any of its solvents, the solution being of a-thiclser consistency than that suitable for the coats 2 and 3. It is also advisable to mix with the solution for the coats 4 and 5 either fibrous, granular or amorphous materials or any combinations of these materials in order to stifiien the coats 4 and 5.

After the coats 4 and 5 are put in place, I apply the coats 6 and 7. The coats 6 and 7 may be composed of various substances, one of the requisites being that the coat 6 will form a firm and lasting union with the 4 coat 5 and that the coat 7 will form a similar union with the coat 6.

I have found that the coats 6 and 7 may be made as above specified for the coats 4t and 5, excepting that any suitable coloring matter may be mixed with the other ingredients in order that the surface cost mayhave the color desired.

I have found that mineral colors are suit the coat 3. These coats are the natural color of thematerials forming same.

The coats 4 and 5' are composed of a substance or substances which give to the-coat l the ability to unite firmly and lastingly with the coat 3 and tolunite similarly with the coat of the materials forming same. These coats may also contain suitable stiffening or binding materials.

The coats 6 and 'T are composed of a suh stance or substances which give to the (i the ability to unite firmly and la; l with the coat 5 and to mile similarly with the coat 7. These coats are colored desired and may also contain suitable stiilicn ing or binding materials.

While I have shown two priming co These coats are the natural color stood that for certain purposes the priming coat 3 may be omittedand the coat 4 applied directly to the coat 2.

is also to be understood that it special I'UlOllHQ is not desired for the floorcovering. the coats 3 and i may be omitted. The surface will then be the natural color of the coating it is to be understood that one priming coat 2 may be applied to the floor 1 and then a coat similar to the coat 4 applied to the coat. 2. This would produce a surface of the natural color of the coat 4, or a coating similar to 6 may be placed upon the coat 4 it coloring is desired.

Hence, it is evident that I may use either a single priming coat and a single coat of uncolored plastic material, or a single coat of priming material. a single coat of uncolored plastic material and a single-coat of colored plastic material; or I may use a plurality of each of said coats.

In carrying out my improved process, l first apply the priming coat- 2 to the floor 1 and allow same to dry and I then apply the other coats, allowing each one to dry before the succeeding coat is applied.

ll hile l have set forth one set of coinl'inations suitable for my improi'ed floor coverings and one process {or applying the some, it is to be understood that the disclosure is for purposes of illustration only and in no-wise to limit thescope of my invention, for many changes may be made in the combinations of the Various coatings and in the process for applying same without departing from the spirit of my' invention.

I claim l. 'ihc herein described process of coating floors which consist in applying a priming coat thereto composed. of a thin solution oi bitumen. in permitting this coat -to dry and then applying'a coat formed of a thick solution of bitumen.

l l "b l f t- .LllC icicin ceccii on process 0 coa mg floors which conslsts 1n applying thereto a pruning coat composed of a thin solution of bitumen, in permitting said coat to dry and then applying acoat composed of a thick solution of bitumen containing stiffening material.

53. The herein described process of coating floors which consists in applying thereto a. priming coat composed of a thin solution of a solid material, in permitting said coat to dry, then applying a. coat composed ol'a thick solution of a solid material, permitting said second-named coat to dry and then applying a coat composed of a ing floors which consists in applying thereto a priming coat composed of a thin solution of a solid material, permitting said coat to dry, then applying a coat composed of a thick solution of a solid material, permitting said sccond-named coat to dry, and then applying a coat formed of a thick solution of solid material containing a coloring substance, both of said thick solutions containingstili'ening materials.

6. The herein described process of coating floors which consists in applying thereto a priming coat composed of a. thin solution of bitumen, in permitting said coat to dry, then applying a coat composed of a thick solution of bitumen, permitting said secondnamed coat to dry and then applying a coat composed of a thick solution of bitumen containing a coloring substance.

7. The herein described process of coating floors which consists in'applying thereto a priming coat composed of a thin solution of bitumen, permitting said coat to dry, then applying a coat composed of a thick solution of bitumen, permitting said secondn'amed coat to dry and then applying a coat composed of a thick solution of bitumen containing a coloring substance and a stillening material.

8. The herein described process of coating floors which consists in applying thereto a priming coat composed of a thin solution of bitumen, permitting said coat to dry, then applying a coat composed of a thick solution of bitumen, permitting said second named coat to dry. and then applying a coat formed of a thick solution of bitumen containing a coloring substance, both of said thick solutions containing stiil'cning materials.

9. A floor structure consisting of a supporting base with layers of bitumcnsuperimposed thereon, the last of said layers containing a coloring substance and a stiffening material.

In testimony whereof, I aliix my si nature.
